PI6C2410LE

Overview

The PI6C2410LE is a low skew, low jitter PLL clock buffer with divider or multiplier capabilities, designed for PCI-X applications in servers and workstations. It features four synchronous outputs synchronized to the input and each other. The device supports selectable input frequency ranges of 10-40 MHz and 40-80 MHz via the HF# pin. It operates on a single 3V to 3.6V supply voltage and is available in a 24-TSSOP surface-mount package. Key electrical characteristics include a maximum output frequency of 133 MHz, low phase error under 150 ps, and an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Four synchronous outputs with independent Output Enable (OE) control for EMI reduction and power management.
• Integrated PLL allows for selectable divider/multiplier functions to accommodate various input frequencies.
• Low timing performance metrics: phase error < 150 ps, output skew < 200 ps, and cycle jitter < 200 ps.
• Supports spread spectrum modulation on the clock input for enhanced EMI reduction.

Applications

• PCI-X clock distribution in server systems.
• Clock buffering for workstation motherboards.
• High-speed digital logic synchronization requiring low jitter.

Procurement Notes

Verify the specific package variant required, as the PI6C2410 series includes both TSSOP (L suffix) and QSOP (Q suffix) options. Confirm that the 'E' suffix indicates Pb-free and Green compliant manufacturing. Check current availability status, as this component originates from Pericom Semiconductor Corporation, now part of Diodes Incorporated, and may have legacy stock implications.

Selection Notes

Select the PI6C2410LE when a 1:4 fan-out with frequency multiplication or division is necessary for PCI-X architectures. Ensure the design accommodates the 3.3V nominal supply voltage. Consider the 24-TSSOP footprint constraints during PCB layout. Verify that the input clock frequency falls within the supported ranges defined by the HF# pin configuration.

Part Context

This component belongs to the PI6C2410 family of PCI-X clock buffers. It was originally manufactured by Pericom Semiconductor Corporation before being acquired by Diodes Incorporated. The 'LE' designation specifically identifies the Lead-Free, Green compliant version housed in the 24-pin Thin Shrink Small Outline Package (TSSOP).

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Diodes Incorporated or Pericom technical support for direct replacements or pin-compatible alternatives.
